“…Thence for scale elimination and cleaning of zinc surfaces by acidic solutions, it is required to use inhibitors [3]. The employment of the plant extracts as inhibitors to lower the dissolution of metals in several typical industrial solutions was performed by several authors [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Inhibitors from plant extracts are characterized by its renewable resources, facilely obtainable, low cost and don't form any harmful effects on the environment [19].…”

Artichoke extract (AE) was studied as the corrosion inhibitor for zinc in 1 M HCl utilizing chemical and electrochemical methods. The adsorption isotherm of Artichoke extract on Zn surface accords with Langmuir adsorption isotherm. The inhibition efficiency increases with increasing the concentration of the extract and decreases with rise in temperature of the medium. The inhibition efficiency reached a value of 93.2% at 300 ppm of extract. This extract may be forming a film and acts as a barrier, which minimize the contact area between zinc surface and HCl solution. Artichoke extract acts as mixed inhibitor in HCl solution. Thermodynamic parameters of activation and adsorption were determined and explained. The adsorption parameters also obeyed the Langmuir adsorption isotherm and the sign of the free energy of adsorption showed spontaneous process of adsorption. The surface morphology of zinc metal was examined by employing various techniques. Also, the biological effect of the Artichoke extract was studied. Theoretical studies of quantum mechanics and molecular dynamics simulations studies were carried out to the Artichoke extract compounds, and the results agree with the experimental one. The efficiencies marked from all employed techniques were in a perfect correspondence, which demonstrated the validity of these procedures.

Plants samples were gathered from Ramadi, University of Anbar. Extraction processes performed from foliage in labs belonging to Center for Desert Studies using methanolic and aqueous extracts to assess their Allelopathy. Allelopathic bioassay applied with three concentrations 0.5, 1 and 2% On Germination%, Germination Rate, Germination Speed, Average Germination Speed, Response Index, Radicle and Plumule Length of wheat seed. Phytochemicals detection of the R. vesicarius presented highest percentage of alkaloids, flavonoids, phenols and Glycosides. GC/MS analysis proofed that R. vesicarius and Z. coccineum methanolic extracts contained highest 2-pyrrolidone-5-carboxylic acid (alkaloid) of 35.98% and 1,2-benzendicarboxyylic acid bis(-methylhexyl) ester (hydrocarbonate chain) of 35.06%, in each species extract, respectively. Methanolic and aqueous extract (%2) of R. vesicarius possessed lowest rate of germination (%13.3), (%50.7), respectively. On the other hand, methanolic and aqueous extract (%2) of Z. coccineum gave lowest germination rate of 30.6 and 81.3%, respectively. so, this extracts of R. vesicarius and Z. coccineum could be used as eco-friendly bioherbicide, and may be integrated into harmful weed control strategies.

Plant extracts represent abundant sources of biomolecules distributed throughout various plant parts. These biomolecules are extracted using diverse solvents and methods. Within these plant extracts lie bioactive compounds, known for their antioxidant properties and anticorrosive capabilities. Detecting and isolating these active biomolecules from plant extracts necessitates analytical techniques such as gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. The active biomolecules within plant extracts contain heteroatoms within their structures, facilitating their adsorption on steel surfaces and conferring corrosion inhibition properties. The advantages of plant extracts as green corrosion inhibitors include ready availability, ease of application, eco-friendly characteristics, and cost-effectiveness. These extracts adhere to steel surfaces, blocking their active sites and effectively reducing the corrosion rate. This review consolidates the findings on the corrosion inhibition potential of plant extracts from various plant parts, elucidating their performance in different concentrations of sulfuric acid.
